Rob McElhenney says the two-against-one rule on Always Sunny has saved them years of emotional arguments because production is too expensive to negotiate every single decision "early on we realized let’s just institute a rule of two against one. And it’s really really and I know it sounds silly and simple but it has been profound" "The assumption is do you trust me? Yes. Do I trust you? Yes. And the three of us trust each other and we trust our taste. So therefore if two of us feel strongly about something then the other one has to capitulate no matter what no questions asked" "They get a chance to plead their case and we all have to remain open-minded. But if the two of us still or two of them say nope this is the way we’re going you move on quickly" "And it actually diffuses so many problems so quickly because you don’t have time as you all know you work in production it’s so expensive to run these shows you just don’t have time to negotiate every single thing and you got to move fast and that has saved us I mean that has saved us hours I would actually say that that saved years of our lives emotionally"
